Solution: move audacity binary to /usr/bin/audacity2, then put the script
in /usr/bin/audacity. Sometimes I've used this technique for example to see
with which arguments is a program calling ifconfig or whatever command. (You
could also debug it anyway). It works fine, although it's a bit hackish to be
honest. Isn't this kind of thing what dtrace brings to the table in
"The reasonable man adapts himself to the world; the unreasonable one
persists in trying to adapt the world to himself. Therefore all progress
depends on the unreasonable man." (George Bernard Shaw)
